Opis:
This paper presents the ways of African swine fever virus (ASFV), transmission to new areas and its occurrence in wild boar and pigs in Poland in 2019. Analysis of ASFV virus incidence in feral pigs and the disease outbreaks in farmed pigs has confirmed that the primary and the only reservoir of the virus is wild boar. In turn, two entirely different routes in virus spreading can be identified. The first one, concerns the spread of ASFV in the wild areas through infected wild boars. Transmission of the virus in this way is slow but steady and gradual. Moreover in these areas the virus also appears on pig farms, but the vector is no longer wild boar. There are so-called mechanical vectors, including largely multi-directional human activities. The second way of ASF transmission results in its spread to areas quite distant from the current occurrence, with the man as the major source of ASFV. Regardless of the routes and possible virus spreading, biosecurity measures should be considered as the primary preventive procedures. The aim of this article was to present and discuss those measures that apply both to pig breeders and all people within the area of occurrence and threat of ASF transmission.

Opis:
African swine fever has emerged in Poland on 14 February 2014. Until the end of July 2021, 12 764 outbreaks in wild boar and 400 outbreaks in domestic pigs have been notified. However, despite the reliable experience gathered during the last 7 years of ASF epizootics in Poland, it is not sufficient enough to prevent further spillover of disease to the distant regions of the country. The most significant aspect of ASF eradication in Poland, is the uncontrolled spread of ASF in the wild boar population. It is important to mention, that the emergence of ASF in wild boar population on that scale has not been identified before, during the disease epizootic in any European or Southern America country. Therefore, the measures undertaken to combat ASF in wild boar are not fully efficient. The ethical concerns, related to massive hunting in order to stop further ASF spread, are raised by pro-ecological societies. According to the food production authorities in Europe, including the European Food Safety Agency (EFSA), one of the most important efforts to reduce further ASF spread and risk of its transmission to domestic pig sector, should be intensive reduction of wild boar population. Taking into account the range of economical loss, due to the ASF emergence in domestic pigs and stamping out of hundreds or thousands pregnant sows, seems not to be not considered by a number of people from pro-ecological societies. Meanwhile, the effective reduction of wild boar population is extremely difficult or even impossible. The most stringent measures of wild boar depopulation may only result in a decrease of 50-60 percent of the entire wild boar number. In contrast, the recovery of wild boar population may reach 300 percent annually. There is no doubt, that wild boar for many years, and perhaps decades, will remain in Europe, including Poland, as the main reservoir of ASFV, and thus a constant epizootic threat for swine production. Other agricultural aspects related to the intensive cultivation of maize and rape, should be reconsidered due to their important influence as a convenient and protein-rich natural feed for wild boar. The success of ASF eradication in Belgium and the Czech Republic shed light on the possibilities of control of this disease in any country of Europe. However, taking into account the focal introduction of ASF to the above-mentioned countries, the strategy of ASF eradication in multi-site affected country as Poland, should be carefully modified and applied as an individual approach.

Opis:
African swine fever (ASF), occurring for many years, is at present the most significant viral disease of swine and wild boar. Despite of the situation, defined as a large epidemic or even pandemic, a vaccine is not yet available, It has been claimed that live, attenuated anti-ASF vaccines are most promising products on the way to control the disease. However the safe and effective vaccine is yet to be obtained. The current status in the field of ASFV vaccine development is encouraging, since ASFV strain(s) have been obtained, that have their virulence genes deleted. Deletion of ASFV genes that inhibit host antiviral type I interferon responses is considered as the most effective strategy to attenuate the virus. Deleted, live vaccinal strain(s) are still able to replicate and encode immunogenic antigens thus induce protective immunity in swine. However, a licensed cell line in which live, attenuated virus (LAV) can be propagated and produced on a large scale, is still not available. Concerning wild boar, the natural reservoir of ASFV, while developing live vaccine for swine protection, rigorous conditions for its safety and efficacy are strongly required.

Opis:
African swine fever (ASF), remains serious epidemiologic and economic concern in pig industry in Europe and Asia. The true rates of ASF spread in the individual countries, affected by this disease, are different from the theoretical scenarios. The most unpredictable factor, which is also crucial in the new episodes of ASF in wild boar observed in the areas thus far free from this disease, is human activity. These areas could be located several to even hundred kilometers from the current region of ASF occurrence in wild boar. An example may be represented by the occurrence of ASF cases in wild boar around Warsaw area in 2017, as well as in western Poland in autumn 2019. Therefore ASF may spread in wild boar population not only in a low, “natural” way, at a rate of 1–2 km per month, but also by human-mediated transfer of the virus at a rate of dozens or hundreds of kilometers. The administrative measures introduced by the Chief Veterinary Officer and the representatives of Veterinary Inspection in Poland, aimed at limiting further ASF expansion in wild boar to northern, western and southern regions. Further scenario for ASF spreading in wild boar and pig population will depend on joint, consistent and effective actions and collaboration between the Veterinary Inspection, hunters and pig producers in Poland.
